4, S25 and as shown in FIG. 10, when the drawer 5 is being drawn out, the second timing flag is turned on after the first timing flag is partially overlapped. Since the signals of S24 and S25 are repeatedly output and given to the control means 8 according to the number of stages of the storage unit 27 that has been pulled out, the main control unit 10 stores the number of stages of the drawer 5 that has been pulled out.

Drawer 5 to the required position as shown in FIG.
When the card is pulled out (S26), a new case 2 of the same ticket type is inserted into the empty storage section 27 (S27). When the case 2 is inserted, the leaf spring 42 is pushed, and the tip of the leaf spring 42 projects to the outside of the drawer 5 (S28). And drawer 5
Is pushed back (S29).

When the drawer 5 is slid in the push-back direction, the timing plates 41 pass through the second sensor 52 and the first sensor 51 in this order. Therefore, as shown in S30, S31 and FIG. 10 of FIG. 9, every time each timing plate 41 passes, the first timing flag (second sensor 52) is followed by the first timing flag ( The first sensor 51) is turned on while partially overlapping. Also, every time the leaf spring 42 passes the third sensor 53, the case presence / absence flag is confirmed to be ON or OFF in the control means 8 as shown in S32. That is, when the first sensor 51 is turned on while the second sensor 52 is turned on, it is confirmed whether the third sensor 53 is turned on or off. It is determined that Case 2 is inside.

Depending on the number of stages of the storing portion 27 to be pushed back, S30,
The signals of S31 and S32 are repeatedly output and given to the control means 8. In S33, the first and second sensors 51, 52 are OFF and the third sensor 53 is turned ON by being blocked by the opening / closing plate 43. As a result, when the opening / closing flag is determined to be ON, the mapping memory 17 of the control means 8 is rewritten. Be done. That is, the main control unit 10 of the control means 8 retains information about how many cases 2 have been inserted before withdrawing, and information about how many stages of the storage unit 27 has been pulled out at the time of withdrawing, Information indicating whether or not the case 2 is contained in each of the pulled-out storage units when 5 is pushed back is recorded in the mapping memory 17 at a position corresponding to the storage unit 27. In other words, the mapping memory 17 contains information regarding the presence or absence of the work in all the storage units 27 at that time, and the main control unit 10 reads and counts the information to determine the number of cases 2 in each drawer 5. Drawer 6
You can see the total number of cases in.

As described above, the ON / OFF signal of the third sensor 53 indicating the presence / absence of the case 2 in each storage unit 27 is recorded in the mapping memory 17 under a certain condition and counted, whereby the number of cases 2 stored in the case 2 is counted.・ Understand the number of payouts and the number of stocks.

Further, in order to prevent an error from occurring when the drawer 5 is repeatedly drawn in and out by an irregular operation, the third
The case presence / absence flag is confirmed using the ON / OFF signal of the sensor 53 only when pushing back and not counting when pulling out.

Further, since the drawer device 6 of this embodiment has the stopper mechanism 30, the drawer slide operation is performed for each number of stages of the storage section 27, and the positioning is reliable. For this reason, there is little risk that an erroneous signal is output from each sensor due to a halfway operation of the drawer 5, and there is an error in counting the slide amount, the sliding direction, and the number of cases of the drawer 5 determined by the signals from these sensors. It is hard to enter.

[0039]

Since the work management device of the present invention detects the slide direction and slide amount of the drawer and the presence or absence of the work in each storage portion by the detecting means during the pulling / pushing back operation, the stock of the work in the drawer is detected. The number can be always grasped, and it is possible to automatically perform accurate product management without any trouble.
